OAuth 2.0
An open standard for granting an app limited access to an account without sharing its password. Strictly it handles authorization; sign-in is usually built on it through OpenID Connect. ZopNight offers Google and GitHub sign-in, and MCP clients can connect through OAuth instead of a pasted token. Why it matters: It avoids long-lived passwords and tokens being copied between tools.
